Hmm, will look into this. It should be the same package name and thus overwrite itself without requiring an uninstall. Also looking into writing to external storage, may even help with other save issues.

Thanks for info, will discuss with them. I believe in this case it was due to the both builds having the same version since the initial one wasn't meant to be released, but got cached during testing, so hopefully that's not the case for all future updates. That said, external storage for save games is likely a smart move regardless.
